Title: Pipe expansion method for seamless tube
Inventor: HIRAOKA NOBUAKI
IPC: B21J5/06
Filed: 1987-11-20
Abstract: PURPOSE:To prevent the buckling and cracking of a pipe by intermittently feeding a tube stock in the gap between the fixed died having an expanded through hole and the movable plug having expanded outer diameter and executing the diameter expansion and thickness reduction of the tube stock by the reciprocating movement of the movable plug. CONSTITUTION:A latchet mechanism 2 is provided at the rod 1a tip of an air cylinder 1 and the fixed die 8 and movable plug 9 executing diameter expanding on a tube stock A1 are arranged. When a tube stock A0 is first intermittently by the rod 1a of the air cylinder 1, the adjacent tube stock A1 is intermittently fed in the gap between the die 8 and movable plug 9. In this case, the plug 9 is subjected to intermittent reciprocating moving with the driving force of a crank mechanism 12 being transmitted via a mandrel 10. The tube stock A1 thus receives diameter expanding and thickness reducing gradually and the inner and outer peripheries are regulated, hence the buckling and crack generation on the inner face are surely prevented.

Title: Grip strength detector
Inventor: SUGIMOTO AKIRA
IPC: A61B5/22
Filed: 1987-11-25
Abstract: PURPOSE:To control a machine on the basis of the grip strength of a hand, by providing a hollow body gripped by a hand composed of an elastomer such as rubber and detecting the pressure in the hollow body changed through the opening provided to the hollow body so as to be opened and closed by a finger. CONSTITUTION:When a hollow body 1 is not gripped, the pressure in the hollow body 1 does not rise and to pressure acts on stretchable conductive rubber 6. When the hollow body 1 is gripped in such a state that an opening 2 is closed by the thumb, the pressure in the hollow body 1 rises corresponding to the grip strength of a hand and, since this pressure acts on the conductive rubber 6, the tensile stress corresponding to the grip strength, that is, elongation is generated in the conductive rubber 6 and the electric resistance of the conductive rubber 6 becomes small corresponding to the grip strength. Therefore, the grip strength acting on the conductive rubber 6 can be detected through the change in the electric resistance of the conductive rubber 6 between a flange part 4, a rubber press plate 5 and a center electrode 9. In order to output a grip strength detection signal, it is necessary to consciously perform operation pressing the opening 2 by a finger. Therefore, trouble such that a grip strength detection signal is outputted unconsciously can be prevented.

IPC: H04B1/74
Filed: 1987-11-25
Abstract: PURPOSE:To reduce the switching time remarkably by adding a command signal of an opposite station to a reply signal with respect to the command signal to switch a reception switch and a transmission switch in the lump. CONSTITUTION:The switching against a fault in a transmission line occurred from a station B to a station A is implemented by changing over a transmission switch 21 of the station B by means of a command signal (p).

Title: Oscillator circuit
Inventor: FURUYA YASUSHIGE
IPC: H03B5/32
Filed: 1989-11-14
Abstract: PURPOSE:To reduce an oscillation self-start time at a low voltage drive by decreasing the capacitance of a load capacitor connecting to an input or output of an inverse amplifier at the oscillation start. CONSTITUTION:Since a drain capacitance is small, the oscillating frequency is slightly deviated from the accurate frequency, but the oscillation circuit rises quickly. Then a frequency divider circuit 32 is operated and a pulse is outputted to an input clock of an oscillation stop detection circuit 31. When several clocks comes to signal 33, since the level of an oscillation stop detection output signal 30 changes from L to H, an N-channel TR 29 is turned on and its drain capacitance changes. The oscillation is unstable at the moment when the capacitance is changed, but the circuit soon reaches the steady-state and the desired oscillating frequency is produced.

Title: Semiconductor device
Inventor: OGURA ISAO
IPC: H01L21/3205
Filed: 1989-11-15
Abstract: PURPOSE:To make a resistance low and to enhance reliability by installing an internal conductor whose one part or whose whole is composed of an ultrafine-particle metal having a particle diameter (a diameter of particles) of 50 to 100Angstrom . CONSTITUTION:A metal is a polycrystalline substance whose particle diameter is normally 100Angstrom  or higher; when the particle diameter is made small, the metal displays a property which is different from that of a bulk metal. For example, when Ti becomes ultrafine particles whose particle diameter is especially 100Angstrom or lower, its bonding strength is increased and its resistivity is lowered. However, when the particle diameter is about 20 to 30Angstrom , the Ti enters a region called a microcluster, and a polycrystalline grain boundary becomes dominant; an energy level is scattered as different from a metallic electric conductivity. When one part or the whole of an internal conductor (e.g. an interconnection, a contact, an electrode or the like) of a semiconductor device is formed of an ultrafine-particle metal with a particle diameter of 50 to 100Angstrom , it is possible to obtain the internal conductor whose bonding strength to a substratum is strong and whose resistivity is small. Thereby, reliability of the device can be enhanced.
